Nasruddin's neighbors hear a loud bang in the night. "What was that?" they ask. "My cloak fell down the stairs," says Nasruddin, "and I was in it!"
Notes: In some versions, this happens because Nasruddin and his wife are quarreling and she pushes him down the stairs.
Here's my short version:
“Nasruddin,” said one of his neighbors, looking very concerned, “I heard a loud banging at your house last night. Is everything alright?”
“It’s fine,” said Nasruddin. “That was just my cloak falling down the stairs.”
“But a cloak could not make such a loud noise!” said his neighbor.
“Well,” admitted Nasruddin, “I was in the cloak at the time.”
